This patch is only valid on NTFS disk. It will create a file with size of 1TB, but occupies only a few disk space. The size of the db file will be truncated to its real size after all data is written done.

Hi @pkrush, as stated in the README of this project the LMDB interface is not working.

Some discussion as been going on about this in this caffe PR.

Also, I just merged a PR by @happynear in my LMDB fork so you might just try to rebuild LMDB. To do so, either go to the download cache lmdb folder and enter:

git pull

or delete the lmdb folder and configure caffe-builder again.

After that build caffe-builder as usual and you should be good to go.

Let me know if this works.

Thanks so much for pointing this out and thanks as well for caffe-builder in general.

Both methods did not work for me. They had the same result as before.

After seeing this post...

It did work fine after lowering LMDB_MAP_SIZE in db_lmdb.cpp
const size_t LMDB_MAP_SIZE = 1099511627776; // 1 TB

My disks are NTFS, on Windows 10.
I made a copy before I did the get pull and liblmdb/mdb.c was updated.

BTW, this is not a big issue to me, I am going to work around it. I am just following up. Also this is a bit over my head. I am just learning as I go here.

Thanks!
